Qwell My Fears

To keep this brief - I may have had an unprotected sexual encounter (the condom fell off some point after I ejaculated, and I’m not sure if I was still inside of my partner for the remaining 15-20 seconds of the encounter - she was just finishing up her period at the time as well, but I didn’t notice any visible blood on me or the condom). I had some flu-type symptoms at about 7 days following the encounter. I have since taken several tests, all with negative results:

I’m just having anxiety about this and would like another opinion on whether I’m freaking out unnecessarily about potentially being positive. I will be following up with another test at the 6 month mark, but just trying to make sure I stay level headed and reasonable right now.
